"Father Gurr presents a record of the appearance of this principle in certain writers and makes an appraisal of its meaning in philosophy manuals. Within the framework of three historical eras, Father Gurr explores the more ultimate meaning involved in the 'common sense' principle, 'Nothing is without a sufficient reason.'" - publisher.
